VALVE.

Application filed February 26, 1917.

'1 '0 all whom z'tmay concern:

Be it known that we, J ()IIN LAMenn'r, J12, a citizen of the United-States, residing at New Rochelle, in the county of l/Vestchester and State of New York, and I-IARRYB. LAM- BERT, a citizen of the United States, residing at North 'Pelham, in the county of NVest chester and State of New York, have invented certain new and useful Improvements inValves, ofwhich the following is ,a full, clear, and exact description.

This invention relates broadly to valves, but especially to those designed for use as inlet and exhaust-valves for fluid pressure engines, motors, or pumps of any form or character, whether using liquids or gases under pressure; but is more especially designed and adapted for use in steam and explosive vapor motors, which valve of our invention is of an extremely simple and cheap form of construction, of little liability to get outv of order, of extreme durability and long life, and practically noiseless in its operation.

Our said invent-ion is fully shown and described in the following specification, of whichthe accompanying drawing forms a part, wherein similar letters and numerals of reference designate like or equivalent parts wherever found 1 throughout the several views, and in which:

Figure 1 is a view in centralvertical longitudinal section of an explosive vapor engine provided with an inlet-Valve, and also an exhaust valve, of our lmproved form;

and

Fig. 2 is aview in detail, on an enlarged scale of one of our improved valves taken in the same central vertical section, of the form shown in Fig. 1, the valve inFig. 2, how. ever, being inverted from the position shown in Fig. 1.

,Referring to the drawing:

The referenceletter A designates the cylinder of an explosive vapor engine, which may be of many and various styles, provided with a watercooling jacketchamber B, connected witha cooling water supply, (not shown), in the usual manner; and having the explosion chamber C in communication with an extension C thereof, in which is located the usual ignition spark-plug D, but the foregoing mentioned structures may be of any suitable desired' form, and no part of our inveatien,

Serial No. 151,029.

As shown in Fig. 1, our improved valve, takes the place of the ordinary common poppet inlet and exhaust valve of the motor, and .is inserted in place in substantiallythe same manner. The reference letter-E indicates-the inlet-valve, and E the exhaustvalve, each of such valves being provided with an actuating shaft, rod or stem 11. and 11 respectively, each of which is reciprocated during the operation of the motor in the Well-l nownmanner common to poppet and other reciprocating.valves, but inasmuch as such reciprocating mechanism is wellknown in the art and forms no part of this invention, we have not deemed it essential to show ordescribe the same herein.

As shown in detail inFig. 2, our improved valve comprises an inside stationary cylindrical wall member or valve-casing piece 2, formed integral with an annular end wall 2', formed intcgral.\vith a sleeve2, which member 2 is provided with an exterior annular male screw-thread 15, at the bottom by which thesame is screwed firmly into position, at the base into a like shaped outer cylindrical casing 1, ofthe same shape and contour as the casing 2, provided at its base adjacentto the screw thread 15 with a like outer annular male-screw thread 16 by which the same is secured in position in the female screw-threaded port G or G, of the motor cylinder according as the same is. to be an inlet or an exhaust valve.

The inner cylindrical member 2 is of shorter length than the outer cylindrical member or shell 1, and a considerable space (according to the size of the valve used, from a half an inch upward), is left between the annular upper end wall 2 of 2, and the upper endwall 1 of 1, and contained and secured in place between the two annular members or shells 1 and 2, is the moving valve-member or shell 3, having the cylindrical portion 3 fitting in the annular-space 17 between the annular-walls of 1 and 2,

and having the end portion or wall 18, from the center of which extends the actuating lift-rod shaft or stem 11 or 11, actuated by suitable cam-mechanism of any suitable well-known form (not shown), which stem 11 or 11' is usually and preferably formed integral with the end wall 18 of the valve member 3.

Located in the moving sleeve valve member 3 and the inner member 2 and forming 7 place;

sembled, and the motor wall-plugs 20 and gas-tight joints between the moving sleeve valve member 3 and the inner-member 2,

and the outer member-1, usually atthe locabut in many cases and for certain purposes,

such rings may be omitted and the joints made sufficiently tight by merely grooving the abutting surfaces. The cylindrical shell or outer-member 1 is provided with a suitable port orports in its periphery indicated by 4:, and the inner cylindrical member or shell 2, is provided with alike port or ports 5, in registry with the port or ports 4 of 1: while the movable cylindrical valve-member 3, reci rocated up and down in. the chamber 1%, by. the reciprocation of the valve-stem 11, is-provided with a port or ports, 6 adapted to be (upon suchrcciprocation) brought into .and out of registry with the port or ports 5. of 2 and the. port or ports 4 of 1, so as to permit of free passage of the fluids through all three of the ports .4, 5, and 6, when they are in registry, andto shut off such passage as shown in Fig. 2, when out of registry. 1 i

In assembling and placing in position, the valve-stem (11 or 11'), is passed down through the sleeve 2 after the placing in position of the piston-rings 7, 8,9, andlO, and the outer-sleeve 1 is then screwed into and the valve havingbeen thus as- 20, (as the icase may be), having been removed, the valves are inserted through the orifices closed by such plugs, and screwed fully home in the female-thread by means of the exterior male screw-threads 16, in themotor enginecasing orifices; the sleeves 2 and stem 11 or 11 passing down through. either theinlet 21 or the outlet 21, as the case may be; the entire valve mechanisms being firmly secured, in place against accidentaldisplacement by a locknut 22 or 22 screwed upon the lower. end of the sleeve 2.

The valve mechanisms being now in position, it will be seen that by reciprocation of the stem 11 or 11, as the case may be, by the usual valve stem-reciprocating mechanism (not shown), that the ports 4:, 5, and

.6, will be brought into and out of registry,

so as to form communication or nonco1nmunication between the explosive chamber C of the motor, and the inlet E or the outlet or exhaust E, thereof.

While we prefer to make our improved valve of cylindrical form, we do not limit ourselves to such construction and formation, andmany changes in the construction and combination of the several parts, may be made without departing from the spirit and scope of our invention.

In like manner the positions of such'valves in the engine, pump, or other apparatus in which the same may be used, may also be widely varied, and when used in double actuating engines or "pu1nps,"it is frequently preferable to have such valves actuated at a right angle to the axial line of reciprocation of the piston, instead of parallel therewith as shown in Fig. 1, as applied to an explosive vapor motor engine.
